Find the circumference.
Use 3.14 for π.
O
r = 6 ft
C = [?] ft
C = πd

Answers

Answer:

37.68 ft

Step-by-step explanation:

Formula

Diameter = 2r (where r is the radius)

Circumference of a circle = πd (where d is the diameter)

Given:

π = 3.14r = 6 ft

⇒ Diameter = 2 × 6 = 12 ft

Substituting the given values into the formula:

⇒ C = πd

⇒ C = 3.14 × 12

⇒ C = 37.68 ft

Answer:

191

Step-by-step explanation:

the rule is +4 so 11+45*4=191 (45 is the number not including the first one)

191 is the answer

Answer:

191

Step-by-step explanation:

First, determine if the sequence is arithmetic or geometric.

If it is arithmetic, the difference between consecutive terms is constant.

If it is geometric, the ratio between consecutive terms is constant.

[tex]\sf 11 \underset{+4}{\longrightarrow} 15 \underset{+4}{\longrightarrow} 19[/tex]

As we add 4 to each term to get the next term, this is an arithmetic sequence with common difference of 4.

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

[tex]a_n[/tex] is the nth terma is the first termd is the common difference between terms

Given:

a = 11d = 4

Substituting the given values into the formula to find an equation for the nth term:

[tex]\implies a_n=11+(n-1)4[/tex]

[tex]\implies a_n=4n+7[/tex]

Therefore, to find the 46th term, substitute n = 46 into the equation:

[tex]\implies a_{46}=4(46)+7=191[/tex]

Triangle XYZ with vertices X ( 5 , 7 ) , Y ( 8 , 3 ) , and Z ( 2 , 3 ) is reflected over the y-axis and translated up 4 units to form triangle X ` Y ` Z ` . What is the length of segment Y ` Z ` ?

Answers

After the reflection and the translation of XYZ, the length of segment Y'Z' is 6 units

How to determine the length of segment Y'Z' ?

The transformation is given as:

Reflection across the y-axisTranslation 4 units up

Both transformations are rigid transformations.

This means that the lengths YZ and Y'Z' would remain the same

The coordinates are given as:

Y = (8,3)

Z = (2,3)

Both points are on the same y coordinate.

So, the length YZ is

YZ = 8 - 2

Evaluate

YZ = 6

Hence, the length of segment Y'Z' is 6 units

Which is equivalent to tan θ?

B secθ/cscθ

C cosθ/sinθ

D cscθ/secθ

Which one is it, and answer quick, and don't be a troll.

Answers

That which is equivalent to tanθ is A sinθ/cosθ

To answer the question, we need to know what tanθ is

What is tanθ?

Tanθ is a trigonometric identity which is the tangent of the angle .

Now, from the unit circle, with radius, r = 1, we have that tanθ = y/x.

Also, the sine of the angle θ is sinθ = x/1 = x

And also, the cosine of the angle θ is cosθ = y/1 = y

Since we have that

tanθ = y/x, sinθ = x and cosθ = y

Substituting the values of the variables y and x into tanθ, we have

tanθ = y/x

tanθ = sinθ/cosθ

So, that which is equivalent to tanθ is A sinθ/cosθ

State the x and y intercepts of 2x+5y=10

PLEASE

Answers

For the x intercept, first plug in y=0 and solve for x.
So 2x+5y=10, is the given equation and then it becomes 2x+5(0)=0, once you plug in y=0.
which leads to 2x+0=10 once you multiply 5 and 0.
So then simplify to get 2x=10
divide both sides by 2 to eliminate 2x so it's 2x/2=10/2.
Then solve for x for both sides so it will be x=5.
The x intercept will be (5,0).

For the y intercept first you plug x=0 and solve for x
So the equation is 2x+5y=10 but now becomes 2(0)+5y=10.
Next multiply the 2 and 0 which becomes 0+5y=10.
Simplify the equation so now it's 5y=10.
Next is to divide both sides by 5 to isolate the y so 5y/5=10/5
Finally y=2
so the y intercept would be (0,2).

1) A school has 1500 students and they are going to vote as to whether they will completely convert the school completely off fossil fuels. How many students would you have to poll to be 95% confident of the outcome within /- 3% of the vote

Answers

Using the z-distribution, it is found that 1068 students have to be polled to be 95% confident of the outcome within +/- 3% of the vote.

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

We have no estimate for the true proportion, hence we use [tex]\pi = 0.5[/tex], and solve for n when M = 0.03. Then:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{(0.5)(0.5)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96(0.5)[/tex]

[tex]\sqrt{n} = \frac{1.96(0.5)}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96(0.5)}{0.03}\right)^2[/tex]

n = 1067.11.

Rounding up, 1068 students have to be polled to be 95% confident of the outcome within +/- 3% of the vote.

how much gift warp is needed to cover a box which measures 3 feet by 2 feet by 3 feet

Answers

4 sides of 3 = 12 feet
2 sides of 2 = 4 feet
12+4 = 16

Answer:

42 ft²

Step-by-step explanation:

You need the total surface area of the box which is shaped like a rectangular prism.

surface area = area of bases + lateral area

Let length = 3 ft, width = 2 ft, height = 3 ft.

The base is a rectangle 3 ft by 2 ft.

The perimeter of the base is 2(3 ft + 2 ft) = 10 ft

The lateral area is (perimeter of the base) × height = 10 ft × 3 ft = 30 ft²

The area of the two bases is 2 × (3 ft × 2 ft) = 12 ft²

The total surface area is 30 ft² + 12 ft² = 42 ft²

8x-9

Step-by-step explanation:

You have to combine like terms in order to simplify this problem.

The like terms you have are 5x, and 3x. If you add 5x+3x, you get 8x.

Now, you do nothing with the 9 because there is nothing to combine it with. For example, if your problem was 5x+3x-9+10, you combine 5x and 3x to get 8x, but now with the 9, you keep the subtraction symbol so it is 10-9, (think of it as -9), and when you finish that, you get 1. Now there are no more symbols so you add, 8x+1.
